Minimally Invasive Surgery       

At Advanced Surgical Care of Northern Illinois, many procedures are performed laparoscopically, with the advanced minimally invasive skills of our expert surgeons. Minimally invasive surgery, also known as MIS, minimal access, keyhole surgery, laparacopic surgery or endoscopic surgery, is a major advance in surgical technique bringing patients excellent results in comparison to traditional ‘open’ surgical procedures.  MIS involves having minimum interference with the body’s normal physiological function thus allowing surgeons access to complex anatomy through very small incisions instead of the large incisions associated with traditional ‘open’ surgery.  Patients often experience less pain, faster recovery, and a shorter length of stay at the hospital.

How is minimally invasive surgery performed?

A tiny camera is introduced into the body through a small incision and transmits images back to a video monitor, thus enabling us to diagnose and treat a variety of conditions.  We insert surgical instruments and devices such as irrigation and drainage devices through the small incisions to assist in treating the condition.
